New DAC, what should I look for?

I currently have a PSA DirectStream Mk1 (modified with APS output transformers and external power supply). Nothing wrong with it at all, but it's the oldest components I have and I'm thinking I may want to try something different. Budget is  ~5k used

The sound profile that I'm looking for is smooth and spacious. Yes, details are nice, but I can compromise somewhat on that to gain smoothness and spaciousness.

The rest of my system consists of PureAudioProject Trio15Classic driven by MasterSound Compact 845. Streamer is Holo Audio Red and Small Green Computer i7 is taking care of the Roon/HQPlayer duties. All cables are Silversmith
